SPECIFICATION forming part of 'Letters Patent No. 423,305, dated March 11, 1890.

Appiiafion fiiea April 29, 1889. ssania. 809,118. (Nomad.)

To all whom, it maty concern:

Be it known that I, J AMEs W. BRooK, of Lynchburg, in the county of Campbell and State of Virginia, have invented a new and useful Improvement in Molds for Ice-Blocks, of which the following' is a specification.

My invention is an improved mold forforming ice-blocks intended, especially, for use inv i binations of parts, as will be hereinafter described, and pointed out in the claims.

In the drawings, Fg'ure 1 is a Vertical section, and Fig'. 2 a transverse section, of my improved mold. Fig. 3 is a detail View of the body-piece of the mold. Fig. 4: is a vdetail View of the socket-forming piece or section; and Fig'. 5 is a detail View of the tenon-forming piece or section, all of which will be dcscribed.

The body or main portion A of the mold is formed, preferably, of thin metal bent into the desired cross-sectonal shape, forming in the construction shown a tapered expansible body-piece and having its adjacent or meeting' edges detaohed, so that the body-piece may be readily expanded to free it from the ice block or section which may be frozen therein. I also taper the mold longitudin ally to further faciltate its removal from the iceblock, and also to facilitate the removal of the tenon and socket forming` sections, presently described.

The socket-forming piece or section Bis fitted to be inserted removably in the large end or base of the body-piece A, and is formed to aet as a plug to close said end, being provided with a core-like piece or stem Z), which projects longitudinally into the body-piece, and in practice forms a socket in one end of the ice block or section frozen in the mold. The

tenon-forming section O is fitted to the small ring's D D, fitted over and pr'essed down on the tapering body-piece.

After ice has commenced to form in the mold the clamping-rings may be removed to permit the expansion of the body-piece when so desired.

In the construction shown the edges of the plate forming the body A are lapped one upon the other; but itis manifest that while such construction is preferred I do not desire to be limited in the broad features of my invention, as the said edges might be slightly separated without involving a departure from some of the broad features, as will be understood.

Now, when the parts are in the position shown in Fig'. 1, and Water is fiowed into or otherwise supplied to the mold and the latter is subjected to cold, either natural or artificial, the water will be frozen in said mold and will take the shape of the interior thereof.. The ice-block so formed will have a socket in one end, resulting' from the core-piece Z), and a tenon or stem on its opposite end, resulting from the socket c. The socket c and core b may be slightly tapered and are fornied of the same size, so that several blocks formed in the same mold may be united to form a post or long' body of ice by fitting'the tenon on one end of one of such blocks into the socket of the next block, as will be readily understood.

It is obvious that the molds may be used in upright position or lying on one side, the Water to be frozen being' properly supplied.

By the described mold the ice-blocks may be quickly formed in short Sections, which can 'then be quickly united to form a firm post of the desired length.

HaVing thus described my invention, what I claim as new is i y 1. A mold for ice-blocks, consisting of the 'body-piece, the socket-forming piece, and the tenon-forming` piece, such pieces being' fitted TOO B, fitted in and adapted to close one end of w such body-piece and provided on its inner side with the stem-like portion b, projecting' a short distance intothe bodyfpiece,the-piece O,fitted in the opposite end of the body-piece and having an opening or socket c,formed"en`- tirely through it and adapted to admit Water to the mold and to form a tenon on `theend Of.
